They both have an egg cell wall, a vacuole, and chloroplast, smooth and rough ER, and much more.
Onion skin is treated to be a tissue because it is thin and - brittle.
The skin cells of the onion get a well which gives- the outer portion its rigid shape.
Red is dominant in comparison to white. Hence there will be more red flowers than white as white it the reccessive genotype.
Because you have to have fossil to make the evolution and it will make it better
Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
